"The ABCs of School Choice" is a comprehensive, data-rich guide to every private school choice program in America. The 2016 edition of "The ABCs of School Choice" is the best yet, not just because of the new look and the fantastic growth in the number of school choice programs, but also because it is now paired with a…

Bullying is one type of violence that threatens a youth's well-being in schools and neighborhoods. The impacts of bullying are felt by individuals, families, schools, and society and may result in youths feeling powerless, intimidated, and humiliated by the aggressive acts of other youth(s). This document is designed as a tool to help…

This article criticizes the term "comorbidity" used to describe the overlap of developmental syndromes or disorders. Data from 179 school-age children are evaluated for criteria of seven disorders. Since fully 50 percent of the sample met the criteria for at least two diagnoses, the premise that these disorders are discrete categories on…

This paper examines the validity of Asperger syndrome as a condition apart from high-functioning autism. Potential differences between Asperger syndrome and autism is possible if both are strictly defined. The importance of genetic factors in Asperger syndrome is stressed. Research on the nosological validity of this condition and its relationship…

This paper proposes "severe developmental disabilities" (SDD) as a useful umbrella term for various severe handicapping conditions such as autism, severe mental retardation, and multiple handicaps. Diagnostic criteria for SDD include language deficiency, disturbed interpersonal relationships, inconsistent response to sensory stimulation,…

Comparison of 19 national data collection programs found significant variability in the disability categories used. Discussion focuses on issues related to improving disability identification in large-scale data collection programs and the effects of these issues on reporting policy-relevant information.

In a field trial addressing revisions to autism criteria in the fourth edition of the Diagnostic and Statistical Manual (DSM-IV), information on 977 cases (454 with autism, 240 with "autistic-like" conditions, and 283 with nonpervasive developmental disabilities disorders) was rated. DSM-IV criteria were compared with the International…

This paper addresses the issues of molar versus molecular assessment of integration of people with disabilities, definitions of integration, and assessment in measuring integration. Measures for four integration components are presented: (1) physical integration, (2) social integration, (3) relationships, and (4) social networks. (Author/DB)

In response to Hallahan et al, the authors suggest that variability in prevalence is a function of the methods used to examine prevalence differences and that the effect specific discrepancy criteria for learning disabilities have on the number of students identified is the critical issue.

This paper considers methodological issues related to the independent variable in early intervention research. Three standards are proposed: (1) use theory to guide research; (2) provide operational definitions of independent variables, quantify them, and describe how they relate to theory; and (3) measure treatment fidelity. Three levels of…

This article reviews the efforts made since 1962 to define learning disabilities, discusses 11 prominent definitions, identifies important conceptual elements on which the definitions differ, and calls for a consensual acceptance of the National Joint Committee on Learning Disabilities definition.

This book is a rare peek into the divergent--and at times contentious--points of view among world's leading researchers on what the condition of mental retardation is and how it should be defined, measured, and implemented in the 21st century. It is a candid and insightful collection of essays from experts on issues ranging from whether mental…

This paper presents a theoretical model illustrating L. Siegel's revisionist conceptualization of learning disabilities and then presents an alternative underachievement model. The paper argues that the alternative model applies standard regression procedures which would lead to a more appropriate definition of learning disabilities and applies…

This study compared 23 children with high-functioning autism with 12 children with Asperger syndrome using DSM-IV diagnostic criteria. Findings indicated few group differences in current functioning but many early history differences. The Asperger syndrome group generally demonstrated less severe early symptoms, a milder developmental course, and…

This critique of a paper by Linda Siegel (EC221505) challenges Siegel's assumptions on the relationship of Intelligence Quotient to learning disabilities as being unacceptable and non-literature-based, and points out that discussion of Intelligence Quotient cutoffs may be moot given that 49 states employ no cutoff for learning disabilities.
